VALENTINE'S 20% OFF*! Limited time only.

A breakthrough in barrier skincare, The INKEY List Ectoin Hydro-Barrier Serum is your winter skin savior—a dual-action serum that boosts hydration up to 10 surface layers deep whilst building a stronger, more resilient skin barrier to defend against cold weather, dry air, and seasonal stressors. Clinically proven to restore skin bounce in just 3 days and deeply hydrate + strengthen the skin’s barrier in just 15 minutes, it’s a cold-weather essential for keeping skin hydrated, soothed, and glowing all season long.

Replenishing your hydration whilst simultaneously repairing your barrier is essential for protecting against winter dryness and moisture loss. Our Ectoin Hydro-Barrier Serum has been uniquely formulated with ingredients that work synergistically to provide deep, multi-level hydration, helping to lock in moisture and shield the skin from environmental aggressors.

2% Ectoin: Known as an extreme protector, Ectoin acts as a natural hydrator and skin cell stabilizer, helping to prevent winter-induced dehydration, calm irritation, and reinforce barrier strength for skin that stays soft, smooth, and comfortable.

Multi-Molecular Hyaluronic Acid: Helps restore the protective skin barrier from the outside in, enabling it to retain moisture more effectively—even in cold, dry air.

Whether you're looking for a hydrating serum for winter-parched skin or a lightweight layer of moisture to keep skin balanced, with continued daily use, this serum visibly improves 5 signs of a compromised skin barrier: dullness, dryness, redness, flakiness, and slackness. The INKEY List’s Ectoin Serum has a lightweight texture that melts into the skin, delivering instant, non-tacky hydration—perfect for layering under your winter skincare and makeup routine.

    Highly recommend this silky serum

    Easy to apply, silky texture. Doesn't leave a residue on the skin. My skin is plumper and less dry.

    New to skincare.

    I am relatively new to skincare and was super excited to try this product as the hyaluronic acid serum reacted with my skin. I do like this product though at times it goes tacky as I’m applying it. I use 2 pumps and I love the initial texture. I will continue to use this product as my skin feels extra hydrated after my moisturiser.

    A Drink for the Skin.

    This treatment cream is so soft on the skin. It is immediately absorbed and really feels like you have given your face a nourishing drink. It is plumping and velvety smooth. A definite must for your skin routine. Highly recommended for mature skin.
